Magmatic Hellkite | Creature | Dragon | Flying
When this creature enters, destroy target nonbasic land an opponent controls. Its controller searches their library for a basic land card, puts it onto the battlefield tapped with a stun counter on it, then shuffles. (If a permanent with a stun counter would become untapped, remove one from it instead.) | Tyler Walpole

Inevitable Defeat | Instant | | This spell can't be countered.
Exile target nonland permanent. Its controller loses 3 life and you gain 3 life. | Cristi Balanescu

Mardu Siegebreaker | Creature | Human Warrior | Deathtouch, haste
When this creature enters, exile up to one other target creature you control until this creature leaves the battlefield.
Whenever this creature attacks, for each opponent, create a tapped token that's a copy of the exiled card attacking that opponent. At the beginning of your end step, sacrifice those tokens. | Chris Seaman

Eshki Dragonclaw | Legendary Creature | Human Warrior | Vigilance, trample, ward {1}
At the beginning of combat on your turn, if you've cast both a creature spell and a noncreature spell this turn, draw a card and put two +1/+1 counters on Eshki Dragonclaw. | Tran Nguyen
